The ability to wirelessly induce an electrical charge from one circuit to another is not new technology. Nikola Tesla successfully pioneered experiments over 100 years ago. We have had electrical toothbrushes for decades. More recently it has become possible to charge some mobile phones without a cable.

The technology is currently in use to charge electrical vehicles without any cables. For example, wireless charging golf buggies and industrial forklift trucks have been available for some time. Operators park over a charging station that automatically transfers power to the batteries.

Big Advantages In The Workplace.

Apart from the ease of use, other advantages include fewer trip hazards from cables. It also eliminates the productivity loss caused when a worker forgets to plug in the vehicle. Many workers would not take the time to plug in a cable if they were only stopping for a short time. With a wireless charging vehicle, there is a power transfer as soon as the vehicle is parked over the charging station and for as long as the vehicle remains there.

But what about domestic electric car users, is there a need for this technology? After all, on average, most people currently only charge once a day, so the extra expense of wireless charging may not be popular. We have the same advantages as mentioned above for the workplace. Fewer trip hazards and helping forgetful users. The latter being especially relevant for parents of young drivers.

How Does Wireless Compare To Cabled Charging?

This is a fast moving technology that will quickly improve. Right now the technology for wireless charging is not as efficient as a cable, there is more electrical power loss during the transfer. It is slower to reach full charge and the equipment cost is far higher.

There are currently no mass produced electrical vehicles that come with wireless chargers as standard. It is possible to purchase a charging station and receiver that would be permanently mounted to the under side of the vehicle. However, this would only be used where you install your charging pad station.

Is This The Future?

In the future, charging stations may be commonplace. All cars may have wireless charging receivers with the ability to receive power at the grocery store, cinema or sports stadium car park, simply by parking your car.
